QUESTION: 9

Direction (Q. No. 9) This section is based on Statement I and Statement II. Select the correct answer from the codes given below.

Q.

Stement I : Second virial coefficient of CO2 is - 0.065 L mol-1 at 400 K and 30 atm making CO2 more compressible than an ideal gas.

Statement II : Compressibility factor of CO2 (Z = 0.945) is less than 1 (Z = 1 for ideal gas) due to the attractive forces betw een CO2 molecules.
